[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Example: Figure 1-3 As shown, the utility model is an aluminum alloy battery core shell air tightness detection device, comprising:

[0031] A sealing test water tank 1, the upper end of which is open, and the sealing test water tank 1 is provided with water for sealing test; and

[0032] The auxiliary mechanism 2 is fixedly mounted on the sealing detection water tank 1;

[0033] The auxiliary mechanism 2 includes a drying component 202 and a driving component 203, and the drying component 202 and the driving component 203 are fixedly mounted on the top of the gantry mounting frame 201;

[0034] The driving assembly 203 includes a cylinder 2031, which is fixedly mounted at the middle position of the upper end surface of the gantry mounting frame 201. The lower end of the output end of the cylinder 2031 passes through the top of the gantry mounting frame 201 and is fixedly mounted with a connecting rod 2033. A mounting plate 2032 is fixedly mounted at the lower end of the connecting rod 2033. Two positioning side plates 2035 are symmetrically fixedly mounted at the lower end of the mounting plate 2032. A horizontally arranged positioning screw 2034 is threaded through the positioning side plates 2035.

[0035] In this embodiment, Figure 4As shown, two positioning screws 2034 are close to each other and one end thereof is rotatably mounted with a positioning head;

[0036] A twist handle is fixedly mounted on one end of the two positioning screws 2034 which is away from each other.

[0037] The aluminum alloy battery core shell can be placed between the two positioning heads, and then the positioning screw can be rotated by twisting the handle to drive the two positioning heads to move toward each other. The two positioning heads moving toward each other can clamp and fix the aluminum alloy battery core shell.

[0038] like Figure 2-3 As shown, the drying assembly 202 includes a hot air blower 2022, which is fixedly mounted on the upper end surface of the gantry mounting frame 201, and a connecting pipe 2023 is fixedly connected to the lower end of the air outlet of the hot air blower 2022, and the other end of the connecting pipe 2023 passes through the top of the gantry mounting frame 201 and is fixedly connected to the left end of the drying box 2021. The drying box 2021 is fixedly mounted on the top surface inside the gantry mounting frame 201, and the inner wall of the drying box 2021 is evenly fixedly connected with a plurality of nozzles 2024. The lower end of the drying box 2021 is open, and the lower end of the connecting rod 2033 passes through the top of the drying box 2021 and the lower end of the drying box 2021 in sequence.

[0039] After the detection is completed, the cylinder 2031 can be started, and the cylinder 2031 can drive the mounting plate 2032 to move upward. The upward mounting plate 2032 can move the aluminum alloy battery core shell upward into the drying box 2021, and then the hot air blower 2022 is started. The hot air blower 2022 can generate hot air, and the hot air enters the drying box 2021 through the connecting pipe 2023, and the hot air is sprayed onto the aluminum alloy battery core shell through the multiple nozzles 2024 on the drying box 2021, so as to dry the aluminum alloy battery core shell.

[0040] like Figure 2 As shown, the mounting plate 2032 is located directly below the drying box 2021 , and the size of the mounting plate 2032 is smaller than the opening size of the lower end of the drying box 2021 .

[0041] This design makes it easy for the mounting plate 2032 to move upward and drive the aluminum alloy battery core shell to smoothly pass through the lower end opening of the drying box 2021 and enter the interior of the drying box 2021.

[0042] The rear end of the bottom of the sealing detection water tank 1 is fixedly connected with a drain pipe, and a switch valve is fixedly installed on the drain pipe.

[0043] By opening the switch valve, the sealing detection water in the sealing detection water tank 1 can be poured out through the drain pipe, thereby facilitating the replacement of the sealing detection water.

[0045] The lifting handle can facilitate workers to lift and transport the utility model.

[0046] During operation and testing, the aluminum alloy battery core shell can be fixed by two positioning heads, and the cylinder 2031 is started. The cylinder 2031 works to drive the aluminum alloy battery core shell to move down into the sealing test water, and observe whether there are bubbles on the sealing test water. If there are bubbles, it means that the sealing is not good.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
